HENDERSONVILLE, N.C. — The new owners of the Hendersonville-to-Brevard rail line have made no commitment yet on using the rail line, which advocates of the Ecusta Trail hope would be converted into a biking and pedestrian greenway. Freight trains that serve 70 miles of the 92 miles of rail Watco Transportation Services bought from Norfolk Southern Railway began rolling under the new Blue Ridge Southern banner on July 26. The Western North Carolina freight service, which Watco refers to as the BLU line, runs west of Asheville and from Asheville to Hendersonville, where it serves Kimberly Clark. The BLU will initially operate with 10 locomotives. Commodities shipped in the North Carolina mountain lines include forest products, aggregates and energy products, Watco said.
